ASCEND Team • • Robert Bearden Dallas Hodge Aaron Petreck Ryan Sallee Clayton Jacobs Kevin Jordan Mo Sabliny
Outline • • Payload Structure Components Specifications of components Software Overall Payload Specifications Conclusion
Payload • Examine carbon dioxide emissions with respect to altitude – Was intended to be on HASP payload, but unable to due to shipping problems • Test structural integrity of Eaglesat structure for future balloon flights
Structure • 3/4 -inch thick hardened foam shell – Thermal insulation • Fiberglass epoxy cap • Built in-house – Cost effective – Experience working with fabrication
Components • • • Arduino Mega Microcontroller Seeeduino Shield compatible with Arduino Carbon Dioxide gas board and sensor Venus GPS antenna and receiver LM 19 Temperature sensor Openlog (SD Card socket) 11. 1 V 2100 mah Li-Po battery Go. Pro Hero 2 Eaglesat Structure Rev 1. 1
Specifications • Arduino Mega – GPS – CO 2 board – Temperature sensor – Openlog • GPS, temperature sensor and open log placed on shield – Require 3. 3 V
Specifications (cont. ) • CO 2 board – Operates at 5 V – Rated to operate to -40 Celsius – Board layout designed in house • Go. Pro Hero 2 – 720 p, 30 fps – Extra battery backpack – Aimed horizontally
Specifications (cont. ) • Eaglesat structure – 1 U (10 cm x 10 cm) – Aluminum 6061
Software • Programmed in Arduino • Sample rate: 1 per second • Temperature and CO 2 readings will be unprocessed • Data Processing (post-flight) – Temperature and CO 2 data points will be entered in a transfer function – Temperature will display degrees Celsius – CO 2 data will read PPM (parts per million)
Overall Payload Specifications • Weight: 3 pounds 1. 5 ounces • Payload string integration method – Lamp rod
